Programmers program the logic of their program in a map and reduce function, and the framework automatically executes those programs on many PCs. All the work of distributing the computation is done by the framework. This includes partitioning the input data, scheduling computation tasks and handling malfunctioning nodes. The abstraction that the !MapReduce framework provides is similar to that provided by the map and reduce (or fold in Haskell) functions found in functional languages. During the talk I will show you how to program using the !MapReduce programming model and tell you how !MapReduce executes your programs. And there is no need to despair if you do not work for Google. There are many !MapReduce implementations, including the open source Hadoop from Apache.
